As expected,there is a noticeable
drop in velocity compared to a full-length
FAL.Black Hills 175-gr.Match load
averaged 2,523 feet-per-second (fps)out
of a standard 21-inch FAL and 2,180 fps
out of the 11-inch barrel.Similarly,
Sellier &Bellot Match dropped from
2,517 fps to 2,190 fps.Radway Green's
147-gr.FMJBT averaged 2,419 fps from
the shorty so there is a significant drop in
power by going to the 11-inch barrel.
Although an eleven-inch FAL still
offers more energy than a sixteen-inch
7.62x39 AKM,the difference in energy is
not particularly great.The significant
advantage of a shorty FAL is a much
wider selection of premium and specialty
loads that are available in .308.
The following stats were from an article by David M. Fortier on an 11" DSA Fal. Add about 70fps for a 13" barrel.
I dont plan on shooting 600yds with it, more like 200-300 max. 150gr Nosler BT at 2450 fps carries over 1000 fp of energy at 300 yds. They work fine on whitetail out of hand rifles. (striker, XP....ect)
